The specific embodiment
The oscillatory type web press 40 of the variable cut-out among the embodiment during Fig. 1 and Fig. 2 show according to the present invention.Roll web 31 unreels from paper roll under the effect that unreels unit 21, thereby leaves when unreeling unit 21 when roll web 31, can be with constant feed speed V
FeedAdvance.Then, roll web 31 enters under the guiding that is positioned at the roller 46,47,48 that unreels 21 downstreams, unit and is positioned at roller 46,47, in the compensator units 32 in 48 downstreams.Roll web is around the path that changes roll web 31 by the compensator in the compensator units 32 22, this compensator 22 is at the run duration of printing machine 40, for example via the driving slide 52 (Fig. 2) that under actuator 126 effects, slides, according to the direction radial oscillation shown in the arrow D1 along horizontal rail.In a preferred embodiment, compensator 22 is air exhaust rod, but in an optional embodiment, compensator 22 can be a roller.After passing through compensator 22, roll web 31 contacts with the roll web driver 23 in compensator 22 downstreams, to adjust the position of roll web 31, wherein said roll web driver 23 is between the operational period of printing machine 40, can be simultaneously along rotatably driving and synchronous of both direction (for example, clockwise direction and counter clockwise direction) with the vibration of compensator 22.Then, roll web 31 enters the Printing Department 42 that is positioned at roll web driver 23 downstreams, and printing element 24,25,26,27 is printed onto image on the roll web 31. Printing element 24,25,26,27 only is exemplary, and can comprise any amount of printing element in theory in the printing machine 40, from 1 to n.In this embodiment, each printing element 24,25,26,27 can be printed onto a kind of image of different colours on the roll web 31, thereby makes printing machine 40 four-color image can be printed onto on the roll web 31.In Fig. 1 and Fig. 2, printing element 24,25,26,27 are schematically shown and have omitted plate cylinder 32 (Fig. 5) for the purpose of clear expression.
In this embodiment, printing element 24,25, the roller 32 in 26,27, each rotates 33,35 (Fig. 5) with constant speed at run duration, thereby makes each printing element 24,25, each all has a constant superficial velocity V roller 32,33,35 (Fig. 5) in 26,27
PuAfter being completed for printing, roll web 31 contacts with the roll web driver 29 that is positioned at Printing Department 42 downstreams, wherein said roll web driver 29 is similar with roll web driver 23, and between the operational period of printing machine 40, it can rotatably drive along both direction (for example, clockwise direction and counter clockwise direction) simultaneously.Then, roll web 31 enters the compensator units 38 that is positioned at roll web driver 29 downstreams, and around by having the path that changes roll web 31 to the compensator 28 of compensator 22 similar structures, with compensator 22 similarly, this compensator 28 is between the operational period of printing machine 40, for example via the driving slide 68 (Fig. 2) that under actuator 128 effect, slides along horizontal rail, according to the direction radial oscillation shown in the arrow D2, near or away from Printing Department 42.Then, roll web 31 is at roller 56,57, and 58 guiding arrives rolling unit 30 down, and at 30 places, rolling unit, roll web 31 is to supply with speed V
FeedBe wound into a paper roll.
Fig. 3 shows roll web 13 and enters printing 42, leaves printing 42 and Fig. 4 shows roll web 13.At printing machine 40 run durations, compensator 22,28 and roll web driver 23,29 all act on roll web 31 harmoniously, with respect to print unit 24,25,26,27 vibration roll webs 31, and handle roll web 31 from unreeling the constant flow of unit 21 to rolling unit 30. Roll web driver 23,29 helps compensator 22,28 to change the direction of motion of roll web in printing by this way.At run duration, roll web driver 23,29 is driven with identical speed with identical direction each other, and between operational period, compensator 22,28 is each other with identical direction and identical velocity fluctuation.Unreel unit 21 with V
UwSpeed move, to unreel roll web 31, then around through compensator 22.Compensator 22,28 is with V
CompSpeed vibrate each other harmoniously near or away from unreeling unit 21, thereby control roll web flowing in Printing Department 42, and the continuity that when the direction of rotation of roll web driver 23 does not stop changing, keeps roll web 31 to flow. Roll web driver 23,29 and compensator 22,28 actings in conjunction are to change direction and to change at the variable velocity V of roll web 31 in printing 42 when printing element 24,25,26,27 does not print roll web 31
Webv, and when 24,25,26,27 pairs of roll webs 31 of printing element print, with constant print speed printing speed V
WebpDrive roll web 31.Wrap-up 30 is with a constant speed V
RwMove, with winding drum paper 31.
As long as the speed of roll web 31 is less than feed speed V in printing 42
Feed, compensator 22 slides off (that is, towards printing 42) from unreeling unit 21, and compensator units 32 plays storage from unreeling the unit 21 continuous effects of supplying with the roll web 31 that comes.As long as the speed of roll web 31 is greater than feed speed V in printing 42
Feed, compensator 22 slides (that is, away from printing 42) towards unreeling unit 21, and roll web 31 is consumed from compensator units 32.Along with printing element 24,25,26,27 pairs of roll webs 31 print, and roll web 31 constantly is consumed in the part at compensator units 32 places.
The feed speed V of the roll web 31 in unwinding device 21 and wrap-up 30
FeedBe less than or equal to printing element 24,25, the superficial velocity V of roller 32,33,35 (Fig. 5) in 26,27
PuWhen roll web 31 leaves the feed speed V of roll web 31 when unreeling unit 21
Feed(it equals the rolling speed V of roll web when roll web 31 enters rolling unit 30
Rw) with printing element 24,25,26,27 in the superficial velocity V of roller 32,33,35 (Fig. 5)
PuBetween ratio be the function of required shearing length (that is printing length).
In an optional embodiment, printing machine 40 can not comprise roll web driver 23,29, and in printing 42, compensator 32,38 can be along printing element 24,25, and 26,27 control flowing of roll webs 31.(non-driven roller or bar can be set on the position of roll web driver 23,29) under the situation that does not have roll web driver 23,29, roll web 31 can quicken individually or slows down by seesawing of compensator 22,28 in printing 42.Move forward compensator 22,28 towards rolling unit 30 and may cause that roll web 31 is carried backward, and may cause that towards unreeling the mobile backward motion compensation device 22,28 in unit 21 roll web is fed forward.In a system that does not have a roll web driver 23,29, the error of alignment may equate with compensator web path length error.
But the use of roll web driver 23,29 (for example, as in the embodiment shown in Fig. 1-4) has improved printing element 24,25,26,27 with the alignment accuracy of roll web 31.In a system with roll web driver 23,29, compensator web path length error may only show as the minor variations of roll web driver 23 tension force, has reduced printing element 24,25 significantly, 26,27 alignment error.
Fig. 5 shows in the printing element 24,25,26,27 of printing machine 40, and for example printing element 24.Printing element 24 comprises plate cylinder 32, blanket cylinder 33 and impression cylinder 35.Plate cylinder 32, blanket cylinder 33 and impression cylinder 35 are driven and have identical peripheral speed (for example, superficial velocity) V
PuPlate cylinder 32 can have a forme 32a who is carrying image, and can accept printing ink from the inking device, and accepts fountain solution from damping device.Forme 32a can be looped around on the part of plate cylinder 32 agley or be looped around agley on the periphery of whole plate cylinder 32.Plate cylinder 32 can print surface with the image transfer of the inking blanket 34 to the roller body 33a of blanket cylinder 33 on, described blanket 34 with image transfer to roll web 31.In this embodiment, blanket 34 has covered half periphery of blanket cylinder 33.The length of blanket 34 can be adjusted between minimum of a value and maximum, to change the cut-out (that is printing length) that is printed onto the image on the roll web 31 by printing element 24.
In an optional embodiment, printing element 24,25,26,27 can be the printed on both sides unit (that is, being arranged to the two sides of roll web 31 is printed) that is formed by another plate cylinder, blanket cylinder, the inking device and damping device replacement impression cylinder 35.
The cylinder 32,33,35 of the printing element 24,25,26,27 among the embodiment during Fig. 6 schematically shows according to the present invention in each 360 ° of rotary course, the speed (V of roll web 31

WebCurve map.The Reference numeral that is used to explain Fig. 6 is used to explain the identical of Fig. 1-5 with those.During the A stage, when printing element 24,25, when 26,27 pairs of roll webs 31 printed, roll web 31 can be with a constant maximal rate V
MaxTravel forward towards rolling unit 30, so make web displacement amount X
WebEvenly rise.The result is, along with roll web 31 is printed in printing 42, and the print speed printing speed V of roll web 31
WebpEqual maximal rate V
MaxBecause blanket 34 has covered half periphery of blanket cylinder 33, half of the once complete rotation of the cylinder of A stage and printing element 24,25,26,27 be consistent.At A after the stage, when each printing element 24,25,26,27 will be separately image each roll web of being printed onto roll web 31 partly go up after, printing element 24,25,26,27 withdrawed from and the contacting of roll web 31 in the B stage, and roll web 31 continues with maximal rate V
MaxAdvance, so make web displacement amount X
WebContinue evenly to rise.In the C stage, the speed of roll web 31 is reduced to 0 velocity amplitude, then along in the other direction (for example, quicken backward), leave from rolling unit 30 up to roll web 31, to such an extent as to roll web 31 has negative velocity with respect to direction of advance, and with minimum speed V
Min(for example, the negative of maximal rate) advances.Therefore, in the beginning in C stage, web displacement amount X
WebIncrease more lenitively, and the C stage midway because roll web 31 has negative velocity, so web displacement amount X
WebBegin to descend.Then, in the D stage, roll web 31 is accelerated to 0 velocity amplitude, then (for example, forwards) quickens once more, reaches maximal rate V up to roll web 31 along inceptive direction
MaxAt preceding half stage in D stage, web displacement amount X
WebContinue to reduce, but at the rear half stage in D stage, web displacement amount X
WebBegin once more to increase.In the E stage, roll web 31 continues with maximal rate V
MaxBe transferred, thus make roll web 31 can with printing element 24,25,26,27 superficial velocity V
PuThe print speed printing speed V that is complementary
WebpAdvance.In the E stage, web displacement amount X
WebIncrease equably.The B stage to E between the stage, roll web 31 not with printing element 24,25,26,27 contacts, this is because half part of blanket cylinder 33 does not have blanket 34, thereby has formed the gap between roll web 31 and blanket cylinder 33 and impression cylinder 35.Then, repeat the A stage, and printing element 24,25,26,27 another images of inciting somebody to action separately are printed onto on another respective roll coil paper part of roll web 31, and this part is closed on each printing element 24, once be printed on the image separately on the roll web 31 before 25,26,27.
Fig. 7-16 schematically shows the process chart that 24 pairs of roll webs of printing element 31 are implemented printing.Printing element 25,26,27 (Fig. 1) are configured to have the form identical with printing element 24, and side by side to implement printing with identical mode of printing mutually with printing element 24.The blanket cylinder 33 that Fig. 7 shows in the printing element 24 is beginning image is transferred to from blanket 34 on the roll web part 31b of roll web 31 (for example, the A stage among Fig. 6).When blanket cylinder 33 was printed onto image on the roll web part 31b, roll web 31 was moved, thereby makes the print speed printing speed V of roll web 31 in Printing Department 42
WebpWith the constant superficial velocity V of blanket 34
PuEquate (for example, V
Webp=V
Max(Fig. 6)).Similarly, when blanket cylinder 33 is printed onto image on the roll web part 31b, printing element 25,26, in 27 each is printed onto image on each roll web part of roll web 31, and this each roll web partly is different from and has been printed each roll web part that unit 24 printed.
The blanket cylinder 33 that Fig. 8 and Fig. 9 show printing element 24 continues that image is printed onto roll web part 31b and goes up (for example, still being in the A stage among Fig. 6).Roll web 31 is still with maximal rate V
Max(Fig. 6) advance and pass Printing Department 24, thereby make the print speed printing speed V of roll web 31
WebpEqual the superficial velocity V of blanket 34
Pu Plate cylinder 32 and impression cylinder 35 are all with superficial velocity V
PuRotation.The roll web part 31a that was printed and be positioned at printing element 24 downstreams by blanket 34 is towards printing element 25 advance (Fig. 1 and Fig. 2).
Figure 10 just shows to finish at blanket 34 and image is printed onto (for example, the B stage among Fig. 6) on the roll web part 31b, and the printing element 24 of blanket 34 after disengaging with roll web 31.Roll web 31 is still with maximal rate V
Max(Fig. 6) advance, and plate cylinder 32 begin with another the inking image be transferred on the blanket 34, be used for the roll web part 31c of printed web part 31b upstream.
Figure 11 shows roll web 31 and advances and do not contact with blanket 34 by printing element 24.Because roll web 31 no longer contacts with blanket 34, thus roll web 31 can with the superficial velocity V of blanket 34
PuDifferent variable velocity V
WebpCarry.At the instant moment shown in Figure 11, the speed V of roll web 31
WebvLess than print speed printing speed V
Webp, and progressively reducing (for example, preceding half stage in C stage among Fig. 6).Because the speed V of roll web 31
WebvFeed speed V less than roll web 31
FeedSo, compensator 22,28 (Fig. 1-Fig. 4) 30 slips towards the rolling unit.Driven roller 23,29 (Fig. 1-Fig. 4) slow down.
Figure 12 shows the speed V of roll web 31 stop motions and roll web 31
WebvEqual for 0 a moment (for example, the interstage in C stage among Fig. 6).Driven roller 23,29 (Fig. 1-Fig. 4) also has and equals 0 speed, and by compensator 22,28, will begin to make roll web 31 along with Fig. 7-Figure 11 in roll web 31 side of advancing quicken (that is, backward) in the opposite direction.
Figure 13 shows roll web 31 and leaves (for example, the rear half stage in C stage among Fig. 6) from rolling unit 30 (Fig. 1). Compensator 22,28 move towards rolling unit 30, and driven roller 23,29 oppositely (for example quicken, counterclockwise), thereby make that roll web 31 can suitably align with blanket 34, and then blanket is aligned and image is printed onto on the roll web part 31c when blanket 34 is returned to the printing position.
Figure 14 shows at roll web 31 and quickens to revert to 0 velocity amplitude, and in printing 42 the speed V of roll web 31
WebvEqual the moment (for example, the interstage in D stage among Fig. 6) after 0.The printing gap of the constantly close printing element 24 of the leading edge of blanket 34.
Figure 15 shows roll web 31 and return back to rolling unit 30 (Fig. 1, Fig. 2 and Fig. 4), and meanwhile, roll web 31 is quickened by compensator 22,28, and roll web driver 23,29 returns to print speed printing speed V
Webp(for example, the rear half stage in D stage among Fig. 6).The phase place of compensator 22,28 and roll web driver 23,29 is configured such that when the leading edge of blanket 34 contacts with roll web 31 the speed V of roll web 31 in printing 42 with speed
WebpEqual the superficial velocity V of printing element 24 intermediate rolls 32,33,35
Pu, and make the leading edge of blanket 34 contact with the leading edge of roll web part 31c.
Figure 16 show in printing 42 roll web 31 with the superficial velocity V of blanket 34 and impression cylinder 35 (for example, the A stage among Fig. 6)
PuThe web velocity V that equates
WebpAdvance.Blanket 34 is printed onto roll web part 31c with image, thereby makes image suitably be alignd on roll web part 31c.Printing element 24 is operated in the mode identical with the mode shown in Fig. 7 to Figure 15, will on roll web part 31c, printing image, and make that roll web 31 and blanket cylinder 33 are synchronous, and then blanket 34 can print another image on the roll web part 31d that is positioned at roll web part 31c upstream. Printing element 25,26,27 in the same way at roll web part 31a, 31b, 31c, the last printing of 31d image, thus make roll web part 31a, 31b, 31c, each among the 31d all is printed with the image of four kinds of colors.
For when a presswork is changed to next presswork, can change cut-out by the printed image of printing machine 40, forme 32a will be replaced with the new forme that carries longer or shorter image, and blanket 34 may be replaced with have with new forme on the new blanket of the circumferential length that adapts of image.Blanket 34 can be the band that adheres to cylinder roll body 33a surface removedly.Cylinder roll body 33a can comprise a mandrel, and a removable sleeve can slide on this mandrel.Removable sleeve can comprise blanket, and this blanket is fixedly attached to sleeve or can be configured and makes blanket can be connected to sleeve removedly.For example, when a presswork a small amount of or moderate (for example, the printed matter of minimum or moderate) need be finished by printing machine 40, blanket 34, with the form of band, can be removed from removable sleeve or be substituted by the required blanket of littler presswork.The vibration ability of printing machine 40 (owing to compensator 22,28 and optional driver 23,29) allows that presswork in a small amount or moderate can be printed machine 40 and finish, and need not to change the diameter of blanket cylinder 33.Same, for example be used for presswork bigger or that occur once more, the sleeve that removable sleeve could be removed and be had the blanket of different size and have a greater or lesser diameter replaces, and printing machine 40 can be with constant speed operation (for example, compensator 22,28 nonoscillatory, and driver 23,29 is with constant speed operation; In fact blanket has covered the whole circumference face of sleeve) or variable speed is moved, and (for example, compensator 22,28 vibrates, and driver 23,29 is with variable speed operation; Blanket has only covered the part of sleeve periphery).Therefore, printing machine 40 can have mobility, and has the different options that tolerable is used to change cut-out.
In addition, when in a presswork specific, that do not require very fast speed of production, printing machine 40 can reduce speed of production easily, and reduces the error that produced by high production speed.But, passing through the vibration of restriction or elimination compensator 22,28 where necessary, and changed the speed of driver 23,29, printing machine 40 can still move with high production speed.
In a preferred embodiment, the length of the printed image of the length of blanket 34 and printing machine 40 is corresponding.In this case, the variation of image length (for example, new forme has the image with before presswork different length) causes blanket 34 to have to be replaced with and the corresponding blanket of image length.In an optional embodiment, blanket 34 can be longer than its length that is printed on the image on the roll web 31, thereby make blanket only just need to change in the length length of image length than blanket 34.If in the change of a cut-out, the length of image may only be that forme 32b need be replaced so, and the behavior of compensator 22,28 and driver 23,29 need be adjusted in the length range of blanket 34.In a preferred embodiment, blanket 34 has covered half of corresponding blanket cylinder 33 peripheries or less than half.
In above-mentioned specification, invention has been described with example in conjunction with specific embodiments.However, clearly, invent under the spirit and the situation of invention scope and can carry out multiple modification and change, the claim that scope of the present invention is square as follows not leaving the present invention the present invention.Specification and accompanying drawing correspondingly conduct schematically show, rather than as restriction.
